Ok l need to hold my hands up now........the pc wasnt shutting down windows had changed the settings to sleep after 10 minutes and as l was just leaving it sat there thats what l did. I am officially a moron
In my defense it looked exactly like a normal start when it was 'turned' on again.
Whatsmore, it is now 100% stable and when l was watching a 4k youtube vid it was boosting to 5.36 - for whatever reason it just doesnt boost when running cinebench r23!?
Also in hindsight l may have got a little paranoid.....
Im sure you will all be pleased to hear lve turned my attention to the graphics card
not that l think there is anything wrong with it, it runs dcs beautifully on my 4k tv (60hz) and also with the meta quest 2 headset it is stunning!
I did run furmark and the score seemed very low, 3700 but l am now downloading 3d mark.
When running furmark it said that amd crossfire was enabled - will this slow things down?
For the record l am going nowhere near amd adrenalin or ryzen master haha
Thank you all for the advice!!!!!!! It is much appreciated.
